Heat shock factor 2-binding protein - Focused Library Design

Available from Reaxense

This protein is integrated into the Receptor.AI ecosystem as a prospective target with high therapeutic potential. We performed a comprehensive characterization of Heat shock factor 2-binding protein including:

1. LLM-powered literature research

Our custom-tailored LLM extracted and formalized all relevant information about the protein from a large set of structured and unstructured data sources and stored it in the form of a Knowledge Graph. This comprehensive analysis allowed us to gain insight into Heat shock factor 2-binding protein therapeutic significance, existing small molecule ligands, relevant off-targets, and protein-protein interactions.

2. AI-Driven Conformational Ensemble Generation

Starting from the initial protein structure, we employed advanced AI algorithms to predict alternative functional states of Heat shock factor 2-binding protein, including large-scale conformational changes along "soft" collective coordinates. Through molecular simulations with AI-enhanced sampling and trajectory clustering, we explored the broad conformational space of the protein and identified its representative structures. Utilizing diffusion-based AI models and active learning AutoML, we generated a statistically robust ensemble of equilibrium protein conformations that capture the receptor's full dynamic behavior, providing a robust foundation for accurate structure-based drug design.

3. Binding pockets identification and characterization

We employed the AI-based pocket prediction module to discover orthosteric, allosteric, hidden, and cryptic binding pockets on the protein’s surface. Our technique integrates the LLM-driven literature search and structure-aware ensemble-based pocket detection algorithm that utilizes previously established protein dynamics. Tentative pockets are then subject to AI scoring and ranking with simultaneous detection of false positives. In the final step, the AI model assesses the druggability of each pocket enabling a comprehensive selection of the most promising pockets for further targeting.

Background:

Heat shock factor 2-binding protein plays a pivotal role in meiotic recombination, essential for spermatogenesis and male fertility. It facilitates the repair of meiotic double-strand breaks, crucial for homologous synapsis and crossover formation. This protein also modulates the localization of recombinases DMC1:RAD51, aiding in the progression past metaphase I.

Therapeutic significance:

Linked to Premature ovarian failure 19, a condition characterized by the early cessation of ovarian function, Heat shock factor 2-binding protein's genetic variants offer a direct pathway to understanding and potentially treating this disorder. Its role in meiotic recombination and double-strand break repair highlights its therapeutic significance.
